Yup, grated raw potatoes. Then put them in cheesecloth and twist the ends... the water will pour out like crazy. I also do the same with grated onions. Use a dash of flour and an egg as a binder too along with some chives, mined garlic, salt, and pepper. Cast iron pan with 1/4" of oil around 375ºF. Add a lump to the pan and then flatten it out with the back of a spoon.

Water inhibits browning whether it's potatoes, burgers, or tofu.

of you could also just do what I do, dice the potatoes and onions and make homefries instead in a skillet :) The onion and potatoes still provide a good flavor but its allittle easier to get the crispyness you want.
